Hybrid Tea Rose plant named `Hadromeo`

ABSTRACT

A new rose cultivar of the Hybrid Tea Class Characterized by having medium sized dark red, loosely shaped, flat, intensely fragrant flowers on a vigorous upright bush. This plant has been designated as `Hardromeo`. It will be marketed in the USA under the tradename of `Olde Romeo`.

The present invention relates to a new and distinctive cultivar of rose plant of the Hybrid Tea class, which was originated by my crossing `Smooth Sailing` (not patented) as the seed parent with the pollen parent (((Old Smoothie×(Polly×Peace))×simon Bolivar))).

Among the novel characteristics possessed by the new cultivar which distinguish it from:

(a) All other cultivars of which I am aware are:

(1) A dark red flower with shadings of magenta on petal outside.

(2) Old rose form being flat, irregular and loose.

(3) Very intense old rose fragrance.

(4) Disease resistant and vigorous.

(b)

Seed parent.--High centered cream flowers.

Pollen parent.--Small dark red flower with 10 petals.

Asexual reproduction of the new rose cultivar by budding, as performed at Tulare, Calif. shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of developement and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new cultivar, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart, e.g. "53A" is plate "53A" of The Royal Horticultural Society Colour Chart.

Parentage:

Seed parent.--`Smooth Sailing` (not patented).

Pollen parent.--(((Old Smoothie×(Polly×Peace))×Simon Bolivar))). Class: Hybrid Tea.
